Boko Haram has released a video showing the abducted students of Government Science Secondary School, Kankara, Katsina state.
Over 300 students were abducted last Friday when gunmen invaded the school.
Leader of Boko Haram, Abubakar Shekau, had on Tuesday said his group was responsible for the attack.
In a new video released today by the insurgents, some of the boys, looking distraught, appealed to the government to cooperate with their abductors so that they can be freed.
Katsina State Governor, Aminu Bello Masari, had claimed that bandits and not Boko Haram abducted the schoolboys.
He said the state government knew the abductors of the children. Katsina police spokesperson, Gambo Isa, was not reachable for comment over the development.
